Abstract: PURPOSE:To simplify the manufacture of upper and lower gate FET by previously forming a spacer film through patterning the film under a semiconductor film being an element-forming film, by removing the spacer film after patterning the semiconductor film and by simultaneously forming a gate oxide film and gate electrode on the both upper and lower surfaces of the exposed part of the semiconductor film. CONSTITUTION:A spacer film 2 is stuck on an insulating film 1 formed on a substrate surface or substrate and patterned into a band shape having a width in the direction of a gate length. Then, a semiconductor film 3 is stuck on the substrate in the manner of covering the spacer film, patterned into a band shape having a gate width in the direction vertical to the gate length, and selectively etched so that the spacer film 2 is removed. Subsequently, a gate insulating film 4 is formed in the exposed part of the semiconductor film 3, a gate material film is stuck on the gate insulating film, both films are patterned into a band shape having the width of the gate length so that upper and lower gate electrodes 5 are formed, and an impurity on the side opposite to the side of the semiconductor film 3 is introduced into the semiconductor film 3 with the use of the gate electrodes as masks so that a source/drain region 3A is formed.

Inventor: TAKAGI YASUTADA
IPC: F02K9/32
Filed: 1986-01-14
Abstract: PURPOSE:To reduce the accumulation of alumina by charging the rear part in the solid propellant charging region with the hardly combustible material having the wall surface directed to the nozzle side at the front edge. CONSTITUTION:In a rocket motor 1, the rear part of a motor case 2 in the solid propellant 17 charging region is charged with insulation 14, and a wall surface 15 directed towards a nozzle 3 side is installed at the front edge of the motor case 2. In the initial period of combustion, a large part of the combustion gas is discharged towards a nozzle injection part 9, forming a uniform stream, and only a slight quantity of the secondary eddy current flows into a space innermost part 18a. In the later period of combustion, the inflow of the combustion gas is weakened by the bottle neck due to the front edge wall surface 15 for the insulation 14, and the secondary eddy current is hardly formed. Therefore, the stay of alumina in the space innermost part 18 is reduced, and the thermal condition of a flexible joint 5 is softened, and the reduction of the responsiveness can be prevented.

Title: Method for reaction control and apparatus therefor
Inventor: YAMASHITA MITSURU
IPC: C08B3/06
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To control a peak reaction temperature with ease and with accuracy, in a batch type reactionprocess for the acetylation of cellulose. SOLUTION: This batch type process for producing a cellulose acetate comprises a preceding step of acetylation under reduced pressure, in which cellulose is acetylated under reduced pressure in the presence of an acidic catalyst such as sulfuric acid, while distilling the vapor phase fraction out of the reaction system for acetylation, and a latter step of acetylation in which the acetylation reaction is rendered to further proceed under a pressure higher than in the preceding step of acetylation under reduced pressure, wherein the higher pressure in the latter step is provided e. g. by stopping evacuation.  In the two-step batch process, the reaction temperature in the latter step of acetylation is controlled by conducting an operation for the transfer from the preceding step to the latter step according to a procedure in which a rate of distilling out of the reaction system in the preceding step is taken as a criterion for the transfer. The operation for the transfer from the preceding step to the latter step may be conducted by taking, as the criterion, a rate of distilling out of the reaction system in the preceding step which is observed after this rate of distilling has reached a maximum value.

Title: Detecting device for projection and recess surface information
Inventor: EGUCHI SHIN
IPC: G06K9/00
Filed: 1986-01-13
Abstract: PURPOSE:To obtain a sharp image which is not affected by totally reflected illumination light by arranging a guiding-out hologram off the optical path of totally reflected light. CONSTITUTION:When a finger 10, etc., is pressed against a recess and projection surface information input part 1a, the totally reflected light 17 after illuminating a projection and recess surface by total reflection travels by repetitive total reflection. Light scattered by a projection part 6, on the other hand, is propagated radially in every direction. Consequently, only the light which is scattered by projection parts 6 is propagated by repetitive total reflection to the hologram 3 arranged off the optical path of the totally reflected illumination light 17 and then guided out of a transparent flat plate 1, but none of the totally reflected illumination light 17 is propagated to the hologram 3. Thus, there is not such a problem that the totally reflected light 17 is incident on the hologram 3 to make its image brighter and the image decreases in contrast. Further, the totally reflected light 17 is only reflected totally in the transparent flat plate 1 and never reaches human eyes when the finger is placed on the projection and recess surface information input part 1a.
